Chrysanthemum plant named &#39;chisel time pink&#39;

ABSTRACT

A new variety of Chrysanthemum plant named ‘Chisel Time Pink,’ having a good uniform canopy of white quill single flowers with pink spoon tips and a light green disc. The new variety has a medium tall vigor, free branching, uniform spreading habit and good foliage presentation.

LATIN NAME OF THE GENUS AND SPECIES

[0001] Botanical classification: Dendranthema grandiflora.

VARIETY DENOMINATION

[0002] The new Chrysanthemum variety denomination is ‘Chisel Time Pink.’

BACKGROUND OF THE INVENTION

[0003] The present invention comprises a new and distinct cultivar of Chrysanthemum botanically known as Dendranthema grandiflora, and referred to by the cultivar name ‘Chisel Time Pink.’

[0004] ‘Chisel Time Pink,’ identified as 21033-0, originated from a cross made in a controlled breeding program in Chichester, West Sussex, United Kingdom. The female parent of the new variety is an undistributed, unpatented seedling identified as P381D4. The male parent of the new variety is an undistributed, unpatented seedling identified as 20398-0 of the unpatented variety known as ‘Kiku Time.’ The new variety ‘Chisel Time Pink’ has been asexually reproduced by vegetative cuttings in Chichester, West Sussex, United Kingdom and the distinguishing characteristics are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

[0005] ‘Chisel Time Pink’ is a Pot type of Chrysanthemum plant variety having white single quill flowers with pink spoon tips.

Comparison with Female Parent

[0006] Plants of the new Chrysanthemum variety ‘Chisel Time Pink’ are dissimilar to the female parent cultivar ‘P381D4’ in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Chisel Time Pink’ differed from plants of the parent cultivar ‘P381D4’ in the following characteristics.

[0007] 1. The new variety ‘Chisel Time Pink’ produces a white quill with a pink spoon tip flower whereas the parent cultivar ‘P381D4’ produces red single flowers.

[0008] 2. Plants of the new variety ‘Chisel Time Pink’ have larger and taller inflorescence than plants of the parent cultivar ‘P381D4.’

Comparison with Male Parent

[0009] Plants of the new Chrysanthemum variety ‘Chisel Time Pink’ are dissimilar to the male parent cultivar ‘Kiku Time’ in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Chisel Time Pink’ differed from plants of the parent cultivar ‘Kiku Time’ in the following characteristics.

[0010] 1. The new variety ‘Chisel Time Pink’ produces a white quill with a pink spoon tip flower whereas the parent cultivar ‘Kiku Time’ produces red single flowers.

[0011] 2. Plants of the new variety ‘Chisel Time Pink’ have larger and taller inflorescence than plants of the parent cultivar ‘Kiku Time.’

Comparison with Other Varieties

[0012] The plants of the new variety ‘Chisel Time Pink’ are similar to the cultivar ‘Scott’ (U.S. Plant patent application pending.) in plant habit and growth rate. However, in side by side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Chisel Time Pink’ differed from plants of the cultivar ‘Scott’ in the following characteristics.

[0013] 1. The new variety ‘Chisel Time Pink’ produces a white quill with a pink spoon tip flowers whereas the cultivar ‘Scott’ produces purple spoon tip flowers.

[0014] 2. The plants of the new variety ‘Chisel Time Pink’ have larger and taller inflorescence than plants of the cultivar ‘Scott.’

BRIEF DESCRIPTION OF ILLUSTRATIONS

[0015] Typical specimens of the plant and flowers for the new Chrysanthemum variety ‘Chisel Time Pink’ are shown in the accompanying digital photograph. The colors shown are as true as possible within the usual limits of this kind of illustration. FIG. 1 is a whole plant view of the new variety ‘Chisel Time Pink’ grown in a pot. The plant shown in the illustration is 55 days from the commencement of Short Days.

DETAILED BOTANICAL DESCRIPTION

[0016] The following description of the new Chrysanthemum variety ‘Chisel Time Pink’ is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom in the month of May. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a pot Chrysanthemum.

[0017] Plants of the new variety have been grown successfully under temperature conditions averaging about 19° C. at night and about 17° C. to 24° C. during the day under light conditions of about 5000 to 6000 foot candles. The plants respond well to the use of growth retardant, such as three B9 treatments at about 2 g per litre. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 1 litre. It has been observed that the shelf life of the new variety is about 21 days with a response time of about 7 weeks. The new variety is suitable for growth in a temperature range of 15° C. to 25° C.

[0018] The following description is with respect to a plant produced as a pot Chrysanthemum. In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
